This past offseason the Mariners made some major changes and with a rather light minor league system it can be difficult prospecting but over 2018 I slowly added a couple of cards of young players to my COMC order. I have made a number of poor prospecting choices over the past 25 years, so I keep my pickups inexpensive.
Here are a couple prospects that I added to my collection:
Braden Bishop- 2015 Bowman Draft Chrome Asia Black Refractor
Evan White- 2017 Bowman’s Best “Best of 2017” Autograph Refractor
Kyle Lewis- 2017 Bowman Draft Chrome Sky Blue refractor
Dan Vogelbach- 2017 Topps Gold Label Framed Autograph
